Objectives

The primary objective is to procure, deliver, install, and commission a single 150-litre electrical steam water-jacketed cooking pot for the main kitchen of Murchison Hospital. The project aims to replace an existing unit while ensuring full compliance with municipal electrical standards, occupational health and safety regulations, and institutional food service requirements.

Scope of Work

• Supply and transport of one 150L electrical steam water-jacketed pot to the hospital site.
• Removal of the existing pot, blanking off the legacy steam line, and replacement of affected floor tiles.
• Plumbing connections for water supply and drainage, including installation of a side-mounted water filler tap.
• Electrical works: running cables from the distribution board to a wall-mounted isolator, installing a 60A circuit breaker, and connecting the unit to a 3-phase, 400V AC power source.
• Mechanical mounting on adjustable stainless-steel legs and secure floor fixing.
• System commissioning, calibration, and functional testing.
• Provision of 80L of cooking oil for future use.
• In-service training for kitchen and maintenance personnel on safe operation and routine maintenance.
• Submission of all mandatory compliance documentation, including a Certificate of Compliance (COC).

Technical Requirements

• Construction & Materials: Inner pan, base, and curb manufactured from 2mm AISI 304 stainless steel; inner petals 3mm, outer petals 2.5mm. Water jacket made from 2mm mild steel fully welded to the inner pan.
• Dimensions & Capacity: Overall diameter 970mm, height 870mm. Total capacity 150L with a water jacket capacity of 39.4L. Weight approximately 180kg (dry).
• Control & Safety Features: Thermostatic control calibrated for 30–150°C, factory-set pressure safety valve, vacuum-proof sight glass, pressure switch to cut power at maximum operating pressure, and a 1¼-inch full-port ball valve outlet with protective step.
• Electrical Specifications: 18kW load (26A per phase), 3-phase, 3P+N (400V) AC, 50Hz.
• Pressure Compliance: Design pressure 125 kPa (124.2°C), maximum operating pressure 115 kPa (122.7°C), test pressure 345 kPa. Must comply with national Pressure Equipment Regulations.
• Finish & Accessories: Polished mirror exterior, spring-loaded hinged domed lid, chrome-plated draw-back-off cook, and safety handles.
• Documentation: Bidders must attach product brochures/pictures, complete and sign the specification annexure, and confirm SABS or equivalent quality standard compliance.

Skills Requirements

• Certified electrical trade qualification or trade test results for safe installation of high-capacity cabling, circuit breakers, and isolators.
• Plumbing expertise for potable water connections and drainage integration.
• Mechanical assembly and calibration proficiency for pressure vessel setup and thermostat verification.
• Instructional capability to deliver practical, in-service training to end-users and maintenance staff.
• Basic construction competency for structural mounting and floor tile replacement.
• Proven track record evidenced by stamped invoices, delivery notes, or job cards from previous similar installations in public or private facilities.

Explanation of Unusual or Complicated Terms

• Water-Jacketed Steam Pot (Phuthu Pot): An industrial cooking vessel that uses a water-filled outer chamber heated electrically to generate gentle, consistent steam. This method prevents scorching, ensures even heat distribution, and enables high-volume institutional cooking without direct flame or dry heating.
• Pressure Vessel & OHS Compliance: Because the pot operates under controlled steam pressure, it is legally classified as a pressure vessel. It must undergo rigorous hydrostatic testing (345 kPa) and incorporate fail-safe mechanisms to comply with the Occupational Health and Safety Act’s Pressure Equipment Regulations, preventing over-pressurisation and potential hazards.
• Certificate of Compliance (COC): A statutory document issued by a registered electrician confirming that all electrical installations meet South African National Standards (SANS 10142-1) for safety, earthing, and load capacity.
• 80/20 Preference Point System: A South African public procurement scoring model allocating 80 points to competitive pricing and 20 points to socio-economic transformation goals. In this tender, full preference points are awarded to companies at least 51% owned by Black South Africans.
